Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Path traversal
EUVDB-ID: #VU20501
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2018-15664
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to perform directory traversal attacks.
The vulnerability exists due to the API endpoints behind the 'docker cp' command are vulnerable to a symlink-exchange attack. A local authenticated attacker can gain read-write access to the host filesystem with root privileges, because "daemon/archive.go" does not do archive operations on a frozen filesystem (or from within a chroot).
MitigationUpdate the affected packages.
Opensuse: 15.1
External linkshttp://lists.opensuse.org/opensuse-security-announce/2019-09/msg00001.html
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Path traversal
EUVDB-ID: #VU20502
Risk: Low
CVSSv3.1: 6.3 [CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-10152
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to perform directory traversal attacks.
The vulnerability exists due to the software does not properly resolve symlinks within containers. A local authenticated attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.
Mitigation
Update the affected packages.
Opensuse: 15.1

3) Heap-based buffer overflow
EUVDB-ID: #VU18302
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-6778
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the tcp_emu() function in slirp/tcp_subr.c. A local user can send specially crafted networking packets, trigger heap-based buffer overflow and crash the affected system.
MitigationUpdate the affected packages.
Opensuse: 15.1
